UNITED STATES PATENT OFFICE.

L. A. DOLE, OF SALEM, OHIO.

MEAT-CHOPPER.

Specification of Letters Patent No. 20,258, dated May 18, 1858.

To all whom it may concern:

Be it known that I, L. A. DOLE, of Salem, in the county of Columbiana and State of Ohio, have invented a new and useful Improvement in Sausage-Meat Choppers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1, is a side elevation of a sausage meat chopper constructed after my invention. Fig. 2, is a vertical longitudinal section of the same, and Fig. 3 is a vertical transverse section of the same.

Similar letters of reference in each of the several figures indicate corresponding parts.

My invention embraces the arrangement of the horizontally slotted reciprocating vertical knife shaft, grooved ways, horizontal crank shaft, central guide and knife supporting tube in combination with the following simple and compact arrangement of gearing for giving a slow horizontal revolution to the meat tube while the knives have a rapid up and down movement; consisting of the toothed rim on the bottom of the tub, loose pinion gearing into the same, loose and fast pinions arranged on the stationary axis of the large driving pinion and two small pinions which are arranged on a shaft passing through the face of said driving pinion and have an independent motion of the pinion while they and it move around a common stationary axis and are actuated by the same crank or belt.

To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

A, represents the tub in which the chopping is performed. It is mounted on four or more legs B, B.

C, is the knife shaft. To its upper end the knives D, D, are securely attached by means of an arch shaped casting E, and screw thread a, as shown. The lower screw threaded end of this shaft rests in a sliding screw threaded, inverted T-shaped step F, being confined in the same by a pin 12. It and the step move up and down together, and are guided in their up and down movements by means of grooved guides c, c, and a tube (Z, the tube being cast with and pro jecting up from the top of the metal bed plate which supports the chopping block, and the grooved guides being screwed to and projecting down from the bottom of said plate. The T-shaped step F, is furnished with an oblong horizontal slot 1, in order to admit the crank wrist g, of the driving shaft G, as shown in the drawing. By thus slotting the step and fitting the crank wrist in said slot a regular and steady up and down movement is secured for the knife shaft and. knives when the shaft G, is revolved, and by guiding the shaft and step as stated the movement is accomplished with very little friction and expenditure of power.

H, is a horizontally toothed rim arranged fast on the bottom of the tub at its outer circumference.

I, is a stationary shaft which has its bearing in one of the brackets h, k, that support the driving shaft G. This shaft has a large driving pinion J, and a small transmitting pinion K, arranged to revolve loosely on it. It also has another small pinion ,L, secured fast on its outer end. The large pinion J, gears into a very small pinion M, on the driving shaft G, the small loose pinion K, into the toothed rim H, and the tight pinion L, into a small pinion N, which is attached fast to a loose axis 0, which passes horizontally through the face of the large driving pinion J, and carries another fast pinion P, which gears into the loose pinion K, and thereby transmits a slow motion to the toothed rim of the tub while the driving wheel J, impels the shaft Gr, through the small pinion M, with a very rapid speed.

lVhat I claim as my invention and desire to secure by Letters Patent, is

The arrangement of the horizontally slotted reciprocating vertical knife shaft C, f, F, grooved ways 0, 0, horizontal crank shaft G, g, and central guide tube cl, for use in combination with the following arrangement of gearing consisting of the toothed rim H, on the bottom of the tub, loose pinion K, gearing into the same, loose and axis and are actuated by the same crank or fast pinions J, L, arranged on the stationary belt, substantially as and ior the purposes axis I, of the large driving pinion J, and two small pinions P, N, which are arranged set forth.
